How does fog see drives in a system

I know that fog does come with a way to make sure it images to a certain drive, I also know that fog uses a Linux layout "sdb1, etc, however I have loaded Linux to see how Linux see my system layout and for some reason fog does not see it the same way. so I am wondering if their is a way to check on how fog identifies your drives?

Make sure you don’t have any SD cards stuck in the system. Also is the hard disk a hybrid drive (flash and mechanical)? Did you install Linux on the system or are you just live booting from a flash drive?

If you setup a debug capture/deploy and then pxe boot a target computer, after a few presses of the enter key on the target computer you will be dropped to a command prompt on the target computer. This is the FOS command shell.

If you key in lsblk it will show you the block structure of the disks that are seen by the OS.
